BRICK AND TILE KlLN.

SPECIFICATION forming part of Letters Patent No. 263,473, dated August 29, 1882.

Application filed June 30, 1882. (No model.)

To all whom it may concern Be it known that we, ROBERT A. BROWN AND JOHN F. BROWN, of Washington, in the county of Daviess and State of Indiana, have invented certain new and useful Improvements in Brick and Tile Kilns; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Figure 1 is a vertical sectional view of our improved brick and tile kiln, and Fig. 2 is a horizontal sectional view.

Like letters refer to like parts in both figures.

This invention relates to brick and tile kilns; and it consists in certain improvements in the construction of the same, which will be hereinatteri'ully described, and particularly pointed out in the claims.

In the drawings hereto annexed, A A represent the end walls, B the back wall, and O the front Wall, of our improved kiln, and D is a partition-wall arranged centrally between and parallel to the end walls, thus dividing the kiln into two compartments, E F, or forming it into a double kiln.

The compartment E, which in the drawings represents a tile-kiln, is heated by furnaces G, located at the end wall, A, and having flues ll extending longitudinally under the floor of said compartment, said floor having openings I for the passage of heat. The ends of the fiues communicate through openings J with vertical concave recesses K in the partition-wall, D, forming continuations of the lines, and terminating under the arched roofL. The wall A is provided with vertical flues M, which are not connected with the furnaces, but which have openings N at their lower ends opening into the compartment E, just above the floor of the latter.

The compartment]? is heated by furnaces 0, located at the end wall, A, of said compartment, and having flues P, extending a short distance and opening directly into said comin one compartment.

partment. The partition wall, D, is also on this side provided with vertical concave recesses Q, forming tlues extending from the floor to the arched roof of the kiln. The wall 0, like the wall of compartment E, has fiues M, with openings N, opening into the kiln. This compartment F is used as a brick-kiln.

lhe partition-wall D is provided at its upper end, just below the roof, with openings R, connecting the flues or recesses K Q in the sides of said wall. Said openings have sliding doors or dampers S.

\Vhen in operation one sideor compartment of our improved double kiln has been burned, the dampers S may be opened, thus admitting the heat from said compartment into the other one, which has meanwhile been prepared for burning, and the contents of which are thus water-smoked. 1n ourimproved double kiln burning may always be kept up It is simple, easily managed, and very economical in regard to fuel.

The compartments E F may, when desired, be constructed alike for either tile or brick.

We claim and desire to secure by Letters Patent of the United States- 1. A kiln provided with a central partitionwall having vertical concave recesses or flues on both sides, and dampers connecting the same at its upper end, as set forth.

2. As an improvement in brick and tile kilns, the herein-described structure, consisting of two separate compartments having furnaces located at the end walls, said end walls having vertical flues opening at their lower ends into the interior of the kiln, and the partition-wall being provided on both sides with vertical concave recesses or flues, and at its upper end with dampers connecting the same, as set forth.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.

ROBERT A. BROWN.
